Object Recognition Image Database
The image sets listed below accompany the publication "Is
colour constancy good enough?" [ECCV '98] .
All images were captured with a Sony DXC-930 3 CDD digital video camera
using the following settings:
-
Gamma Correction : OFF
-
Colour Tempurature: 3200 K
Each object in the database was placed in a Macbeth Judge II light booth,
and an image was captured of the object under five different illuminants.
The camera aperture was adjusted to prevent image clipping under the brightest
lighting conditions for a given object, and not changed between illuminants.

Image Sets
The image database consists of two sets, the Model and Test databases:
-
Model Database - images of objects in a fixed orientation, captured under
5 different illuminants.
-
Test Database - images of objects in a random orientation, captured under
the same 5 illuminants as the model database.
Example of model
and test images for "ball2".
